Assessment of Environmental Toxicities of Linear Alkylbenzenesulfonates (LAS) Including LAS Complexes (LAS-C), Alkylphenolpolyethoxylates, and Their Biodegradation Products
Autor: Akiko Utsunomiya
Publikováno v: Journal of Health Science. 45:70-86
Linear alkylbenzenesulfonates (LAS) and alkylphenolpolyethoxylates (APE) are shown to belong to a major group of surfactant as ingredients of detergents and are normally present in raw sewage. Many biodegradation products of these surfactants, such a

Toxic effects of linear alkylbenzenesulfonate and quaternary alkylammonium chloride on Dunaliella sp. as measured by 1H-NMR analysis of glycerol
Autor: Tomohiko Watanuki, Isao Tomita, Akiko Utsunomiya, Kazuhiro Matsushita
Publikováno v: Chemosphere. 35:1215-1226
A new method to assess the toxic effects of linear alkylbenzenesulfonate (LAS : alkyl carbon number; 12) and quaternary alkylammonium chloride was established by using living green alga, Dunaliella sp.. This method is based on the 1 H-NMR determinati
